Charging directly to rechargeable battery pack
Charging to the laser
Note:
When the power indicator light is flashing on the charger, the battery
is low and the life of the battery can be extended when charging
the battery in its lowest voltage. Charge the rechargeable battery
every two or three months if the laser will be unused for a long
period of time.
Before Using Your Laser Level
When you charge the new battery or one which has not been used
for long periods of time, it may not reach full charge until after
you have discharged it fully in use and recharge it several times.
Instrument Usage
1. Put in Ni-MH rechargeable battery pack, or 4 “C” alkaline batteries
(not included, except in 40-6526), or connect the 6V DC battery
adaptor to the unit’s power jack.
2. Place the laser on a platform or tripod, connecting with tripod to
the 5/8" screw thread at the bottom of the instrument.
Note: If the laser is inclined beyond the self-leveling range, the
laser will deliver an audible alarm. You will need to re-position the
laser inside of its self-leveling range.
